Step 1

In a small bowl, combine brown sugar, smoked paprika, kosher salt, chili powder, onion powder and garlic powder.

Step 2

Trim the pork tenderloin of any excess fat and silverskin. Pat the pork dry, and then rub the spice mixture all over the meat.

Step 3

Allow pork to sit at room temperature while preparing the grill.

Step 4

Preheat grill to medium heat and brush the grates with vegetable oil (to prevent sticking).

Step 5

Place pork on the grill. Close the grill and cook 15-18 minutes, turning every few minutes to ensure even cooking. The meat is done when it reaches an internal temperature of 140-145 degrees F. You can baste with the barbecue sauce during the final 1-2 minutes, or just serve warm barbecue sauce alongside the pork for dipping.

Step 6

Remove the tenderloin to a cutting board and allow the meat to rest for about 5-10 minutes before slicing and serving.
